SPRINKILING AND FLUSI-IING HYDRANT.

Specification of Letters Patent.

Application filed June 17, 1913.

Patented Feb. 16, 1914. Serial No. 774,109.

To all whom it may concern Be it known that I, FRED B. MUELLER, acitizen of the United States, residing at Decatur, in the county ofMacon and State of Illinois, have invented new and useful Improvementsin Sprinkling and Flushing Hydrants, of which the following is aspecification.

This invention relates to an improved sprinkler and flushing hydrant,and has for its principal object to provide a hydrant for attachment tothe city main or supply pipe independently of the usual fire hydrant sothat water may be drawn off for sprinkler wagons, for flushing, forcontractors use, and for any other purpose without interfering with theuse of the fire hydrant.

Among the more or less important objects of this invention are thefollowingto provide a hydrant of this character with a stop and wastecock located at the lower end of the hydrant near the connection betweenthe same and the main, and a hose valve at the upper end of the hydrantnear the surface level of the pavement and to which may be attached anysuitable hose or pipe coupling; to provide means on the hydrant foropening and closing the valves independently of one another from thesurface level of the pavement or street; to provide the hydrant with acurb box inclosing the hose valve and in which the valve is locked fromremoval by means located beneath the curb box so that the valve cannotbe detached by unauthorized persons and only by removing the earth frombeneath the box and lowering the same; to provide in general a simplecompact structure comprising relatively few parts which may be easilyassembled and taken apart, and to provide a drain for the curb box tocarry off any waste water collecting in the box to a sewer or a likepoint of discharge away from the lower parts of the hydrant.

Other objects and advantages of this invention will be brought out inthe following detailed description of one embodiment of this invention,and in the accompanying drawings in which like characters of referencerefer to similar parts throughout the several views, and in which Figure1 is an end elevation of the hydrant shown as attached to a main, partsof .the hydrant being shown in section. Fig. 2 is a side elevation ofthe hydrant, parts of the same being shown in section. Fig. 3 is adetail sectional view taken through the lower end of the curb box on theline 33 of Fig. 1. Fig. t is a detail fragmentary view of the side ofthe cover for the curb box.

Referring to these drawings, the reference numeral 10 designates themain or supply pipe to which is attached a corporation cock 11 carryingupon its outer end areducer 12 in which is threaded one end of aconnectlng pipe 13. A street L 14: is mounted upon the end of theconnecting pipe 13 and is adapted for attachment to the improved hydranteither directly or by the use of a connecting pipe or the like so as toenable the positioning of the hydrant at the desired p ace.

1V ith particular reference to Fig. 2 it will be seen that the L 14: isattached to the inlet end of a combined stop and waste cock 15, thelatter having a supply pipe 16 attached to its outlet end and extendingupwardly from-the cock 15 toward the surface level of the street orpavement. The cook 15 may be of any adaptable construction and isprovided with an operating valve stem 17 which rises from the cook 15and is elongated to dispose its upper end near the surface level of thestreet. The stem 17 is provided with a polygonal head 18 upon its upperend for the reception of a special wrench by means of which the cook 15may be opened or closed.

The upper end of the hydrant is provided with a curb box 19, of anypreferred form, and into which project the upper ends of the supply pipe16 and the stem 17 The opening in the bottom of the box 19, into whichprojects the upper end of the supply pipe 16, is surrounded by apolygonal boss 20 receiving therein the correspondingly shaped base 21of a hose valve 22 located in the box. The base 21 is fitted in the boss20 and rests upon the bottom of the box providing a shoulder between theopening for the pipe 16 and the boss 20. The supply pipe 16 carries alocking ring 23 engaging against the underside or bottom of the box 19,and held in such position by set screws 24-. The valve 22 is threadedupon the upper end of the supply pipe 16 and is held from rotation uponthe supply pipe 16 by the boss 20. The collar 23 holds the valve 22 fromforward displacement from the boss 20 to thereby prevent the removal ofthe valve by unauthorized persons.

The valve 22, as clearly shown in Fig. 1, is provided with a lateraloutlet branch 22 threaded at its extremity for the reception of a hoseor pipe coupling, and projecting forwardly within the box and upwardlyto a point near the top thereof, so that access may be readily hadthereto. The valve 22 isin other respects of ordinary type and isprovided with a valve stem 25 having a polygonal head for the receptionof a special. wrench for opening and closing the valve 22.

The cock 15, which is embedded to a considerable extent in the earth, isprotected by a hood 26 which surrounds the cock 15 and has recesses inits opposite sides through which pass the inlet and outlet ends of thecock 15. To the upper end of the hood 26 is attached preferably bythreads, a pipe or casing 27 rising about the stem 17 and projectinginto the box 19. The upper end of the housing or pipe 27 is threaded toreceive thereon a threaded cap 28 binding against the bottom of the curbbox 19 and supporting the casing 27 and hood 26 in their properposit-ions. A locking ring or collar 29 surrounds the casing 27, issecured thereto by set screws 30 and binds against the underside of thebottom of the box. Thus the easing 27 is held from displacementlongitudinally thereof. The cap 28 is provided with a suitable bushing31 through which passes the stem 17. Thus the valve 15 is protected fromthe drainage of water from within the box and also from around the box.

The curb box 19 is provided with an opening 32 in its bottom and intowhich is threaded or otherwise suitably secured a drain pipe leadingdown from the box 19 and discharging at any suitable point,asinto asewer or the like. The drain pipe 33 is adapted to draw off any overflowor waste water collecting in the box 19. A cover 34 is suitably hingedat one side of the box and is adapted to close down flush with the topof the box so that no portion of the hydrant will project above thesurface level of the pavement into which the box is sunk. This cover 34,as may be seen from Figs. 1 and l, is provided with an inset portion 35which is apertured to receive a stem 36 having a polygonal head 37 forthe reception of aring by means of which the stem 36 is adapted to beturned. A locking disk 38 is secured upon the lower end of the stem 37and against the under flat side of the inset portion This disk 38carries a locking flange or finger 39 engaging beneath a lip 40extending inwardly from the front side of the box to lock the cover 34closed. The disk 38 is further provided with a recessed projection 41into which is seated a spring 42 bearing at its outer end upon a ball 13engaging against the lower face of the inset portion 35. This insetportion 35 has a recess 1 1 in its underside into which the ball snaps,by the action of the spring 42, to hold the disk 38 in looking position,and is pro vided with a second recess or depression 45 spaced circularlyfrom the recess 44: and adapted to receive the ball l3 and hold the disk38 yieldingly in an open or unlocked position.

When the device is in use and it is desired to draw the water from thehydrant it is only necessary to apply the proper tool to the head 37,turn the disk 38 by means of the head to unlock the cover 34, whereuponthe cover may be raised. The hose or pipe is now attached to the branch22*, the stems 18 and 25 being now turned to release the water from themain 10 into the supply pipe 16 and up through the valve 22 and branch22 into the pipe or hose. hen it is desired to shut off the flow ofwater from the hydrant it may be done by simply closing the valve 22 andallowing the cook 15 to remain open.

The advantage of having the valve 15 is when any repairs are to be madeto the valve 22, or to any parts of the hydrantbeyond the cook 15, thiscook 15 serves the purpose of shutting off and preventing waste of thewater from the main.

It will be understood from the above description that the valve 22cannot be rotated to unscrew the same from the supply pipe 16, fromwithin the box 19, until the earth beneath the box 19 is removed, theset screws 24; and 30 loosened and the collars 23 and 29 slipped downupon the supply pipe 16 and the casing 27, respectively. The box 19 mustnow be moved down upon the supply pipe 16 and the housing or casing 27to disengage the boss 20 from the base 21 of the valve. The valve 22 maynow be rotated and removed from the supply pipe and the box 19. It willbe seen that any waste water collecting in the box 19 cannot flowthrough the bottom of the box down upon the supply pipe 16 and the cook15, since the boss 20 serves as a closure for the opening which receivesthe supply pipe, and the cap 28 constitutes a closure not only for theupper end of the casing or pipe 27 but also for the opening whichreceives the pipe 27. The waste water in the box 19 must pass outthrough the drain 33 and be thus discharged into the sewer or any otherdesirable place at a distance from the lower end of the hydrant.

It is to be understood that the above description and accompanyingdrawings dis-' invention provided only that such construction becomprehended within the following claims.
